Fill 'Er Up With Frankenfuel

ETHANOLThe original gasoline alternative (and a common additive) is produced by fermenting and then distilling corn or sugar. But even billion-dollar subsidies and other inducements haven't made ethanol competitive with gasoline. Research - most notably in genomics - now focuses on making it from less costly waste cellulose. Corn stalks and husks provide a ready supply, but novel crops like switchgrass might be more efficient.
